Yeah, don't trust the Western localisations because the developers had nothing to do with that.

They could still be Bowser Jr's cousins though, and then we'd know that Bowser had a brother called Morton if that held true. In any case, related or not, they're still the same characters they always were.

No there not you can't establish some them as being Bowser's kids and then just drop that for no reason.

Even if it had been that way (which there's no indication of there being in Japan), you could very easily drop it because it has never affected the games in any way.

I don't want to believe this. I have many good reasons.*Reason number one: The Koopa Family seems more in1complete without them.*Reason number two: The Koopalings are more unique than Bowser Jr., NOT that i dislike him or anything. Each Koopaling has its own personality. Bowser Jr. is just a young Bowser who likes painting (Also, note that he bears a huge resemblence to Baby Bowser from the Yoshi series and especially Mario & Luigi:Partners in Time.)*Reason number three: If you combine the traits of each koopaling, you'll get what Junior's mother looks like.*Reason four: It just raises more questions. How did they come to be? Do they still call Bowser dad? Are they adopted? Are they Bowser clones?*Reason five: As a Koopaling fan, I don't want to think of them as adopted/cloned nobodys.
